1.3.4 Output devices - printing technology

Question 1

What are output devices?

Answer 1

devices that take data processed by a computer and turn it into a human-readable form

Question 2

What are the two types of inkjet printers?

Answer 2

thermal bubble and Piezoelectric crystal

Question 3

how to thermal bubble printers work?

Answer 3

heat from resistors within the printer causes ink to vaporize and form tiny bubbles. As each bubble expands, ink is ejected onto the paper.

Question 4

How do Piezoelectric crystal printers work?

Answer 4

The crystal vibrates in and out when it receives an electric current. Ink is ejected when it vibrates in and new ink is drawn to replace it when it goes out.

Question 5
